NASA Mars Rover Curiosity Looks at Ground Ahead, Moons Above

Phobos in Transit

Mars has two small, asteroid-sized moons named Phobos and Deimos.

A series of daily drives has taken NASA's Mars Rover Curiosity to a vantage point about halfway to a science destination area called Glenelg. The rover has been using its Mast Camera to examine the area ahead and also to catch special occasions when the Martian moons Phobos and Deimos pass in front of the sun from the rover's point of view.
